EMG nerve conduction studies can only assess large fiber polyneuropathy.
Small fiber cannot be evaluated by EMG nerve conduction study, but it may be assessed by skin biopsy..

This can offer a clue in diagnosing various nerve and muscle conditions. Learn more in 10 Conditions Diagnosed With an EMG.
